Fukushima, in 2024,is a city of 272569 inhabitants. If that’s unlivable, I’m fine with it. Hiroshima, Nagazaki and Chernobyl are all inhabited too.
Saying that nuclear stuff makes places unlivable is plain wrong, it’s anti-science. It’s comics level of bullshit science. Travel in time is a more serious theory than nuclear stuff destroying the planet.
There is no chance it wasn’t meant to be an open world. The witcher 3 was a very successful open world they made.
Also, CP77 actually is in the style of elden ring that was praised for it, but CP77 came long before it. Most critiques of CP77 missed that part because the game doesn’t throw it at your face.
